Dennerle - Utricularia graminifolia

Introduction:

Utricularia graminifolia, widely known in the hobby as UG, is a unique and eye-catching carpeting plant native to Southeast Asia. Belonging to the carnivorous Utricularia genus, UG is notable not only for its delicate, grass-like leaves but also for its ability to form soft, vibrant green carpets across the aquarium foreground. Although it possesses tiny bladder traps underground, its carnivorous nature is subtle and does not interfere with tankmates. With its fine texture and luminous appearance, UG is prized in high-tech aquascapes and nature-style layouts for creating lush, meadow-like landscapes.

Care Requirements:

• Water Parameters:

  • Temperature: 20–28°C

  • pH Range: 5.5–7.0

  • Hardness: Very soft to moderately soft water (1–6°dGH)

• Nutrient Requirements:
  Utricularia graminifolia prefers nutrient-poor substrates and can struggle in rich aquasoils. It absorbs nutrients directly from the water column, so light liquid fertilization is ideal. CO₂ injection is highly recommended and often essential for healthy, compact carpet growth. Avoid overfeeding or excess organics, which may hinder its delicate root system.

• Tank Setup:
  Best suited for foreground use, UG grows well in fine sand or inert gravel but can also be established carefully in aquasoil if well maintained. High lighting is critical to encourage tight, low growth. Gentle water flow helps prevent algae buildup and delivers CO₂ and nutrients evenly without disturbing its shallow root system.

Care Tips:

Start with tissue culture or clean, pest-free samples, and plant UG in small clumps spaced apart to allow it to spread. Maintain high CO₂ and stable, soft water conditions for optimal health. Trim the top lightly to encourage horizontal spread and denser coverage. Be vigilant with algae control, as its slow growth and fine leaves are vulnerable to competition.

Utricularia graminifolia (UG) is a stunning, velvety carpet plant that transforms the aquarium foreground into a vibrant green field. Its elegant leaf structure and fine texture make it a centerpiece in high-end aquascapes, ideal for aquarists seeking refined beauty and willing to provide stable, supportive conditions.
